SAM is designed for simple and intuitive operation. The User Interface
provides quick interpretation of the ight information displayed.
The central Control Knob can be located at the bottom-center, middle-
left or middle-right of the unit bezel depending on the installation
orientation. This is the only user interface device on the unit.
The Control Knob has two functions: Push and Turn.
The Control Knob provides 16-detents per revolution and typically
changes the information it is controlling on the display one unit per
detent or click.
The Push function is used to select the highlighted option in a menu
or to enter and exit menus and control functions. The Push function
can also perform certain operations with a push-and-hold action.

In Pre-ight Mode, power is applied to the unit and the Introduction
Screen appears during startup (Image 1).
During Pre-ight Mode, the Introduction Screen will be displayed
while the unit conducts an initial Power-up Built-in Test (PBIT) of
the system to validate operational readiness. This includes, among
others, a battery capacity measurement, an internal test to verify
software and memory, and conrmation that the internal settings
and identication of the unit match the Conguration Module
installed in the aircraft cable harness.
The Introduction Screen will be displayed for approximately ve
seconds and will transition to Flight Mode when complete.

The Attitude Indicator portion of the display (Image 4) will always
appear on the top display when oriented vertically and can be
congured to appear on the right or left display when oriented
horizontally.
The Attitude Indicator consists of seven parts: Horizon Line, Sky
(blue), Ground (brown), Symbolic Airplane, Roll Scale, Pitch Scale
and Slip Indicator.
The Symbolic Airplane will always remain in the center of the
display, with the background elements moving behind it to represent
the aircraft’s position relative to the horizon. The symbol that represents
the airplane can be selected during Flight Mode using the Options
Menu (see Options Menu, page 21).
The Roll Scale is depicted as an arc of graduations representing
bank angles of 0° (triangle), 10°, 20°, 30°, 45° (small triangle) and 60°.
The Roll Scale can be congured during installation to be xed to the
sky/horizon or xed to the top of the display. The unit is operable and
usable in a continuous and unlimited roll range of 360°+.
CAUTION: The roll conguration must be set to match other
attitude indicators in your panel.
The Roll Pointer is the triangle just below the Roll Scale and represents
the aircraft in relation to its bank angle. It is congured, by denition,
to operate conversely to the Roll Scale behavior. That is, a rotating
Roll Scale produces a xed Roll Pointer and a xed Roll Scale
produces a rotating Roll Pointer.

The Pitch Scale is depicted as a series of graduations representing

numbered. The unit is operable and usable in a continuous and
unlimited pitch range of 360°+.

A series of chevrons (^) will appear overlaid on the Pitch Scale
at attitudes greater than ± 45°. This is to indicate to the pilot the
direction of the horizon for quick reference when in an unusual pitch
attitude (Image 5). The chevrons always point toward the horizon line.
